Communication method, apparatus, and device

Abstract

In a communication method, a terminal device sends uplink data corresponding to M HARQ processes, and receives first indication information, where the first indication information indicates whether to start a DRX uplink retransmission timer corresponding to N HARQ processes in the M HARQ processes; and the terminal device starts the DRX uplink retransmission timer when the first indication information indicates to start the DRX uplink retransmission timer, and receives second indication information when the DRX uplink retransmission timer runs, where the second indication information indicates retransmission of uplink data corresponding to the N HARQ processes. The terminal device can determine, in time based on the first indication information, whether to start the DRX uplink retransmission timer. A terminal device is configured with computer instructions to perform the described method.
